4citizen of the inited States, and a resident paint solutions onsurtaces, such as oilcloth,

i One object of my invention is to simplify llr'e construction of the blocks of the block printing machine and to insure the proper "and arenrate transference of the paint coinpons?! Yfrom each block to the surface ofthe material being printed.

` Afin-ther object -o'ftheinvention to .ulcsgn' the block 'so .that it 'willrhold a given *qi'laf'nti'tv 'of paint and while the block is rec- `taifgn'ila`-r in eross'section it'.y will make .a cn'- eular deposit ofpainton prepared sur-- face.

`ai portion ofl these ribs so that the deposit' of paint made by theblocks onto the surface ofthe oilcloth consists of a series 'of short and long lines. By my invention the pattern ismade up oi` a series of'eircular deposits or' `paint evenly distributed over the surface -and 'the pins are so arranged that ,the deposits substantially .touch one another,4 as in the higher grades of this 1naterial it is. desired to Cover as much of the surface of the original material as possible and it is also essential 'that the deposits shall be uniform and that the continuity of the design shall be unbroken.

Referring'to the drawings. 1 is 'ametallic plate. 2. 2 are the pins, which 'are integral with the plate and 'this plate is secured to "the-block '3 n1 any suitable manner., A

number of these plates placed side by side 'form the printing block. AIt isthe present practice-to arrangethe pins about twelve tothe inch and the spaces between the pins equal their width. Each pinis preferably ycrucittnm in cross section. as clearly shown y in Figs. 3, 8. and 9, although Ait may be four-sided. and each side coneaved. as in Fig. 11.or`the pin may be made as in Fig. 12 in which there is la rectangular recess in each side. By forming the pins in this `manne-r the paint applied to the ends'i'f the pins. as in lTig. 5. will' adhere to the' sides tliereofmore readily than if the pins had flatsides ln order to strengthen the pins, Vpreterably taper them. as illustrated in Figs; 2 n nd 4. and it will be understood that they are cast of a. con'ruoostionV resembling '.yvpe'metl. In making these pin plates a puur-h is used. which is of theexaetshape of the pin and impressions Aare made in` a wooden block, preferably bass wood. vby heating the 'punch and burningtlie block `to form a cantv of agven depth. These' cavities are a given distance apart deter 4mined by the particular design it is desired to form. Then a casting is made, using the blo'ck as a mold.. This is a comparatively cheap lnethod 'of making a printing 4plate and the plates can be made a certain size and can he arranged side -by ,side over the entire surface ofthe printing block, as in Fig. 1.

-The entire pressions are made in the wooden blocks which form the molds so that the impressions oI" one block will have a, .given rela# designis formed when the in1- departing from my invention." tion.
